Misconceptions. Students may think that distance and displacement are the same. The terms sound similar, which may cause students’ confusion. Remind them that distance is the length traveled while displacement is the distance and direction between the initial position and the final position.

These equations can be derived through algebra. Equations 1 and 2 define velocity (v = d/t) and acceleration (a = ∆v/t). Equation 3 comes from the fact that ∆v is v – v 0. a = (v – v 0)/t rearranges to v = v 0 + at. Equation 4 is derived from the fact that when velocity changes gradually, the displacement that occurs is the same as it would be if the object had the average velocity the ...

This problem can be solved using kinematic equations, but it is much simpler using a conservation of energy approach. All that is necessary is to set the initial energy of the block equal to the final energy of the block. Velocity is then easily determined. Mechanical Energy. Mechanical energy includes both kinetic and potential energy.

Kinematic Concepts: sublevels 1 and 2. Motion can be described using words, diagrams, numerical information, equations, and graphs. Using words to describe the motion of objects involves an understanding of such concepts as position, displacement, distance, rate, speed, velocity, and acceleration. Vectors vs. Scalars. 1.
